THRASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 324,997, dated August25, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, JONATHAN Hnnsrr- BERGER, a citizen of the UnitedStates of America, residing at lV-alnut Creek, in the county of Holmesand State of Ohio, have in vented certain new and useful Improvements inThrashing-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to combined thrashers and grain-separators havingaseries of heaters extending from the thrashing-cylinder back to thetail of the machine, and provided with a closed bottom consisting ofinclined sides, and a central trough having an endless grainconveyer;and'the invention consists of the operating parts combined with theother parts of the machine, all arranged as hereinafter fully set forthand claimed.

In the accompanying drawings, Figures 1 and 2 are side elevations. Fig.3 is a top view with.

the cover removed. Fig. 4 is a vertical longitudinal section on line atm of Fig. 3. Fig. 5 is a cross-section on line 11 y of Fig. 4.

The running-gears A, the supporting-frame and inclosing sides B, thethrashing'cylinder G, the fan D,the tailings-elevator L, thegrainreceptaele F, and conveyer F are all constructed and arranged inthe usual well known manner.

G G designate radially-winged feeders arranged,as shown, between theheaters and the thrashingcylinder, to revolve in reverse directions, asshown by arrows in Fig. 4 of the drawings, for the purpose of feedingthe straw from the thrashing-cylinder to the heaters.

H designates a series of heaters extending from the feeders the entirelength and to the tail of the machine. Several heaters composing therear portion of the series are axled on a horizontal plane, and theother heaters are axled on a plane inclined downward tothe feeders. Oneend of the axle of each of these heaters is provided either with a dish,a, ora pulley, d or 7t, to which are eccentrically attached bycranlrpinsthe pitman-bars a a. The forward end of the bar (1. is, inlike manner, eccentrically attached to a pulley, a, on one end of theaxle of the feeder G, which pulley carries a hand, a, which is crossedand extended over the pulley a on one end of the axle of the feeder G,by means of which de vices the feeders are rotated in reversedirections, as shown by the arrows.

The motive power which operates the machine may he applied to a pulley,b, on one end of the shaft of the thrashing-cylinder, or to a pulley onany other operating shaft. lVhen the power is applied to the pulley b,the power which runs the feeders, heaters, fan, and other portions ofthe machine is conveyed from the pulley b on the other end of thethrasher-cylinder to the pulley b on one end of the shaft of the firstheater and pulley I) on the end of the fan-shaft, as shown, the motivepower being conveyed to the other heaters by the connecting pitman-bars.

The bottom of the thrasher consists of the sides c,fitted closely to thesides B of the machine, and are inclined inward and downward to acentral trough, d, securely attached to the inner edges of the sides 0.This bottom, filling the entire space between the sides,exlends from thefront end of the thrasher to and over the inner portion of thegrain-board in the rear end of the thrasher, thus completely closing thelower portion of the thrasher and preventing any grain from fallingthrough the machine to the floor or ground.

The trough is provided with an endless apron, f, furnished withtransverse cleats f, which apron runs over rollers 0 0 at the ends ofthe trough, for the purpose of conveying the grain to the grain-boardK,plaeed over the riddle c and screen 0 at the rear end of theseparator. The endless belt f is run by means of a belt, d, extendedover a pulley, d on the shaft of one of the heaters, and over a pulley,d, on one end of the shaft of roller 0. Endless bands It, provided withtransverse slats h, are arranged to run over rollers If h at the ends ofthe grain-board K. These hands are run in the direction indicated by thearrow in Fig. 4 by means of the belt k, extended over the pulleys 7s 7:?on the end of the shaft of the rear heater and the roller h", for thepurpose of carrying off the tailings which may fall upon thegrain-board.

The grain-conveyer F is run by means of a belt, or, extended over thepulleys m m on the ends of the shafts of the fan and the conveyer.

L designates an inclined railings-elevator provided with an endlessconveyor furnished of the machine being closed by the close bottom andconveying-trough, no grain can pass downward to the floor or ground, andthe entire upper portion,from the feeders to the tail of the machine,being used for beaters, allows the number of heaters to be greatlyincreased, which increased number of beaters increases correspondinglythe agitation of the straw and the more thorough separation of the grainfrom the straw.

The dispensing with the vibrators and the webs ordinarily employedallows the machine to be constructed about three feet shorter,and thethrashing-cylinder to be placed about fifteen inches lower than themachines having the vibrators and webs. And this machine runs moresteadily and is less liable to be moved from its position than a machinehaving vibrators, which shake the machine so as to render it difficultto fasten it so it will not be moved toward the engine.

A machine reducedin its depth and length, as described, evidently costsless and is better adapted to be well balanced on its runninggears thana deeper and longer machine.

As the straw passes under the thrashing cylinder it is carried by thefeeders to the beaters, and is kept in constant agitation by thecontinued series of beaters till it passes off at the tail of themachine, and the grain,being thus thoroughly separated from thestraw,descends into the central trough and is conveyed to thegrain-board, and is subjected to the fanblasts as it passes through theriddle and screen to the grain-receptacle.

What I claim as new, and desire to secure by Letters Patent, is

Athrashing-machine comprising the toothed cylinder 0, the winged feedersG G, the series of beaters H, extended from the feeders to the tail ofthe machine, the disks a, and pulleys b d k on the shafts of theheaters, the pulleys b b on the shaft of the cylinder, the pulleys a aon the shafts of the feeders, the fan D, and grain-conveyer F, thepulleys b m m on the shafts of the fan and conveyer, the pitmanbars a aeccentricall y attached to the disksa and to the pulleys a d k,theinclosed bottom consisting of the inclined sides 0 and centraltrough, (1, extending from the front of the ma chine to and over thegrain-board, the beltrollers c c", and the endless belt f, arranged torun on the rollers in the central trough, substantially as and for thepurposes described.

In testimony whereof Iaffix my signature in presence of two witnesses.
